1 Claim.

This invention relates to a pump, mainly designed for irrigation purposes, the general object of the invention being to provide a pump which can be sold at low cost and one which will move the maximum amount of water with minimum amount of power.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views," and in which:-

Figure 1 is an elevation of the improved pump.

Figure 2 is a top plan view thereof.

Figure 3 is. a section on the line 3-3 of Figure 1.

Figure 4 is a longitudinal sectional view through the pump.

Figure 5 is a bottom plan view of the bowl with the bottom plate removed.

In these drawings, the numeral I indicates the bowl of the pump which is composed of a large cylindrical casing, the bottom of which is closed by a plate 2 bolted to the bottom flange of the casing as shown at 3 and having an eccentrically arranged coupling pipe 4 formed therewith, this coupling pipe being adapted to be bolted or otherwise fastened to the suction pipe 5. An impeller A is located in the bowl or casing and is composed of the lower ring-shaped plate 6, the curved blades 1 having their lower edges suitably secured to the upper face of the plateand the upper cover plate 8 which has its lower face secured to the blades. The hub of the impeller is' shown at 9 and the inner ends of the blades are secured thereto. The opening in the plate 6 is located above the bore of the coupling pipe 4 while the upper plate 8 is located close to the top of the casing I which has a threaded nipple I0 thereon for receiving the closed lower end of a small cylinder II which forms a bearing for the shaft I2, the lower end of which passes through the bottom of the cylinder II and is attached to the central portion of the upper face of the plate 8 of the impeller. The hub 9 has a depending part terminating in a conical or substantially semispherical head I3 which finds a bearing in the spider I4 in the coupling pipe 4. A second nipple I5 extends upwardly from the top of the casing I at one side thereof and remote from the nipple I0 and this nipple I5 receives the lower end of the outlet pipe It. A substantially semi-circular bafile plate I? is arranged in the casing I and partly encircles the impeller and a second bailie plate I8 is located in the casing I and extends from a portion of the first plate I! to the opposite side wall of the casing and is located to one side of the plane of the nipple I5 and these two plates form a chamber IS in the casing I so that the water drawn into the casing or bowl I by the impeller will first flow into the chamber I9 and then pass from the chamber through the nipple I5 into the pipe I5.

The upper end of the outlet pipe I6 is formed with a spout 20 and its upper end is closed by a cap 2| having a small discharge valve 22 thereon so that a hose or the like can be connected with the valve to direct a small stream of water from the pump to a radiator or other object.

The pipe I6 and the cylinder II are connected together by the clamps 23 and a clamp 24 supports a bearing 25 from the upper end of the pipe I6, this bearing supporting the upper end of the shaft I2. A lubricant cup 26 is carried by the bearing 24 and a pulley 21 is attached to the shaft I2 between the bearing 25 and the upper end of the cylinder II This cylinder II is adapted to be filled with oil or other lubricant and is closed by a cap 28 provided with a packing gland 29.

It will be understood that when the shaft I2 is driven, any suitable source of power and the impeller will act to draw water or other fluid up the pipes 5 and 4 and discharge it into the chamber I9 of the casing I whence it will flow up the pipe I6 and escape through the spout 20 and if 3 the valve 22 is open some of the water will pass through this valve into a hose or the like connected with the valve. The oiling system keeps water from the bearings and makes the pump easy to operate. As before stated the pump is mainly designed for irrigation purposes where it is difficult to keep bearings free of water. However, it will be understood that the pump can be used for other purposes.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What is claimed as new is:-

A pump of the class described comprising acircular bowl having an inlet opening in its bottom located to one side of the center of the bowl and an outlet opening in its top located to the opposite side of the center, a discharge pipe having its lower end in communication with the outlet opening, an impeller in the bowl including a bottom member having a centrally arranged opening therein registering with the inlet opening, a vertically arranged substantially semi-circular partition member extending from the top of the bowl to the bottom thereof and partly encircling the impeller, a smaller curved partition member extending from the top of the bowl to the bottom thereof and having one side edge connected with the first partition member a slight distance from the inner side edge thereof, the outer side edges of the two partition members being connected at spaced points with the internal side wall of the bowl, the second partition member being slightly spaced from the plane of the outlet opening with the concave face of said small partition facing toward said plane, the concave faces of both partitions facing in the same general direction, a verticallyarranged tubular member closed at its lower end and said end being exteriorly threaded, a. threaded nipple on the top of the bowl concentric to the center of the impeller and into which the threaded end of the tubular member is threaded, a shaft passing through'the tubular member and connected with the impeller, means for rotating the shaft, the tubular member containing oil and a packing gland in the upper end of the tubular member through which the shaft passes.
